In his first-ever interview, the sole Australian survivor of the Waco siege has revealed to 60 Minutes what really took place during the 51-day stand-off, and why he believes crazed cult leader David Koresh will one day return to Earth as the son of God.

Tears also roll down the cheeks of the series' host Gus Worland as he listens to the conversation outside the room.

Later on in the discussion another boy spoke about how he blamed his parents for their separation and the negative effects it had on him while another student spoke about his affection for his mother that he was often disrespectful towards.

The episode and the boys' openess won high acclaim on social media where viewers said they too had been driven to tears and praised the program as "mandatory viewing".
